Emu
Deep, resonant booming grunt 'e-moo', often repeated 3 times. Females give a deep drumming call produced by an inflatable throat pouch. Generally low-pitched and far-carrying.
Geographic Range & Migration

Throughout mainland Australia. Absent from Tasmania, where the Tasmanian emu was driven to extinction by 1850.
